Drippers are the best flavor and clouds. The only issue with them is that you have to keep dripping into them apposed to tanks. If you don't want a lot of vape (I hear some people are weird like that) then clearomizers are for you. RTAs are a middle point in that you can build the coil and have a tank, but it wont be as good as a dripper.
Personally, if you are starting looking to try things out I would recommend the CLT2 by infinite or a clone for a dripper. It is easy to build and cheap. For a RTA I love the orchid V4 but I hear the rose is also good. For both, go for the clones as originals are very expensive.
The best way to find what you like is to try things out.
